Southern Australia faces high fire danger this autumn
Australia just recorded its second hottest summer, with southern Australia continuing to experience drought heightening fire risk in autumn.
The Australasian Fire and Emergency Services Authorities Council (AFAC) released their autumn bushfire outlook for 2025 on Thursday, February 27, showing an increased fire risk stretching the coastline from Carnarvon in WA down towards the Gippsland in Vic.
The red shading on the map below shows areas that have an increased risk of fires over the next three months. The remaining grey areas on the map have a near-normal risk of summer fires, according to the AFAC outlook.

A key driver behind the high fire risk forecast in the south is the severe rainfall deficiencies that parts of Australia have been experiencing in over a year. The lowest rainfall on record was recorded in the past twelve months across parts of southern WA and SA and western Tas.

Summer was also very dry in these areas, particularly for the southern districts of SA. In addition to the dry weather, Australia saw its second-hottest summer since national records were first kept in 1910, while it was the hottest summer on record in Western Australia. The hot and dry weather across southern Australia during summer meant that vegetation has dried out, making it more flammable.
As we head into autumn there are no major climate forcings for rainfall across southern parts of Australia and the models below show a lower chance of wetter than normal conditions in the coming months.

This rainfall forecast means that conditions should continue to be dry with increased fire risk across the south of the country in the coming months. Meanwhile, temperatures are forecast to be above average in autumn, although by mid to late autumn the risk of heat will lower significantly.
